Verification Regulations for Ammonia Gas Detector
1. In my opinion, pay attention to the installation method of the ammonia gas detector.
2. Ammonia gas is a light yellow gas, poisonous, and its hazard safety level is 2.2.
3. The partial density is 0.7714g/t.
4. The vapor pressure is 1013.08kPa (25.7°C).
5. The explosion limit of steam and air mixture is 16-25% (the most flammable concentration is 17%).
6. According to the national standard "Occupational Exposure Limits of Hazardous Factors in the Workplace GBZ", the maximum allowable concentration of ammonia in the workshop is 30mg/M3, which is only about 39.5ppm.
7. From actual testing, generally refer to the following values.
8. Threshold Average (TLVTWA).
9. 25 (generally set after the third-level alarm point) TNUMBERAP threshold (TLV-STEL).
